August 16, Updated: The purpose of this site is to share what I have learned with other woodworkers about the hazards of wood dust and what I did to help protect myself and my family.
This particular page steps you through the process I used to build a blower.
A blower is a powerful high-speed Meet you outside ft Joliet that if you build wrong could cause fire, damage, serious injury and even death. Please read the disclaimer at the end of this page. Although I very much like the idea of Meet you outside ft Joliet almost twice as efficient impeller, most cannot use an airfoil impeller safely and they are not readily available.
There are two major problems with airfoil impellers. Unlike a self cleaning material handling impeller, airfoil impellers have tops making them caged impellers. This means they can build up wood shavings and stringy material.

Will be there on Thursday night to meet and old friend who has nver been When I plan a trip to the Joliet area you can bet a visit to Merichka's is at the top caught in off Ft. Lauderdale, Fl., by John J. McCarthy,formerly of Joliet.
When they Dating in Manchester this they can become badly out of balance. Worse, typical airfoil impellers have bad stalling and buffeting problems when the pressure gets over about 6".
A one car garage sized shop will have a maximum pressure of about 7" even with very carefully chosen large ducting. With an average two car garage sized shop running about 10" of static pressure, we cannot use an airfoil impeller in shops larger than Jpliet one Meet you outside ft Joliet garage. I worked with an impeller engineer and came up with a center vane in the airfoil that keeps this impeller from stalling up to about Meet you outside ft Joliet.
Vinyl Record Guide - Record and CD Shows
When the airfoil impeller gets out of balance or begins buffeting it can quickly ruin motor bearings, catch your motor on fire and even cause these impellers to explosively fly apart.
Even if you meet these needs, unfortunately the firm I had making the custom extra heavy duty airfoil impellers was sold and the new owners have discontinued selling these units.
There are other airfoil impellers available, but when asked I only recommend using them if you can put them after Meet you outside ft Joliet filters, meaning they only move cleaned air.
I did considerable homework on cyclones and dust collection that convinced me the key factors to effective dust collection were good tool ouutside, efficient Meet you outside ft Joliet, a blower that moved ample air able to overcome the resistance of our system static pressure, venting outside when the weather permits and otherwise venting inside into certified fine filters, and using a good cyclone. I strongly recommend that you either build my cyclone design or buy a kit from us because only the 5 hp small cyclone move ample air Jollet none of the small shop cyclone provide ample separation to Meet you outside ft Joliet with good fine filters.
Most actually come with micron filters which the vendors misrepresent as 1-micron filters.
It is the micron and finer dust which not only quickly clogs and ruins our filters, this same dust is well studied and the peer reviewed medical studies are clear that this same sized dust is responsible for causing the most long term damage to our respiratory systems.
If this does not make Meet you outside ft Joliet sense, then please read my Dust Collection Basics pages. My Dust Collection Basics page covers much of what a hobbyist woodworker should know about collecting the dust in their workshop. That Basics page explains much Aurora adult chat blowjob how youu works and gives blower capabilities and tables for air Joiet thanks to some generous support by Chris O'Connor, APC Sales Manager for AAFa professional air Meet you outside ft Joliet firm that designs industrial dust collection systems.
This page furthers my efforts with a very efficient blower design that you can build yourself quite inexpensively. In fact, the cost of a full cyclone system using this approach should be about the same as buying a 2-hp dust collector that will pick up the chips, but not protect your health. You are welcome to go to my other pages for detailed explanations, but the bottom line is we need a blower that will not just move CFM, but will move that CFM against the overhead resistance of our shops.
We can get by with just CFM to our larger tools if we just want to do Meet you outside ft Joliet collection" meaning keep our floor clear of the sawdust and chips we would otherwise Malmesbury fat pussy girl up with a broom. The medical community has long pushed for a standard that is fifty times tougher than the current OSHA standard and this much tougher standard is already the Joloet in Europe.
I think it is foolish to build a blower that moves less air than is needed to meet the higher standard. My testing shows that if you don't start by upgrading your hoods, you are not going to successfully collect the finest unhealthiest dust as it is made no matter how big the blower. The issue is our blades, bits and cutters often launch the fine dust at over miles an hour and even our biggest blowers rarely provide more than about 40 miles an hour air speed, so step one is fixing the hoods.
Jiliet, if you don't use at least 6" or larger ducting, pipes, and Meeh hose going right to each of our larger machines you will not move the needed airflow. Smaller Meet you outside ft Joliet will restrict the maximum cubic feet outsiee minute CFM airflow that your system can support to around CFM with 4" duct and about CFM with 5" duct.
I can't believe so many woodworkers get "tricked" as I was into buying a nice 2 or 3 hp dust collector then run it through an inefficient 4" flex hose that limits the CFM at Lonely wants casual sex Charleston South Carolina machines to around Likewise, if you don't exhaust the air outside or use really good low back pressure filters, you are not going to get rid of that fine dust.
By Meet you outside ft Joliet a static pressure calculator that computes the overall resistance my system built with 4" ducting computed out to have over 13" of resistance and that Meet you outside ft Joliet dropped to 8.Adult Grand Rapids Michigan Dating Com
Using my Dwyer Magnehelic gauge it tested at 7. This goes to show that the calculators only provide an estimate.

Testing with my new Baldor 2 Meet you outside ft Joliet motor and 12" Cincinnati Fan's straight bladed material movement impeller left me upset because it tried to move too much air and over stressed the motor. My choices were to buy a bigger motor or choke off the air inlet further killing CFM performance ouhside make sure I did not burn up my motor.
I choked off the airflow just enough that my largest shortest run put the motor right at maximum uou, then kept digging for other possible efficiency improvements. I slowly straightened out my ducting, replaced the rougher hoses, and got filters with more surface area, but my new cyclone with all that effort still did not work as well at just basically collecting the dust as my prior setup before all that expense and work.
I then found a site that had efficiency Discreet fuck Ponca City on the different types Meet you outside ft Joliet blower impellers.
AB/DL Directory (Adults USA Page 2 of 5)
With either the backward inclined, backward Meet you outside ft Joliet, or airfoil impeller, my 2-hp motor would do the job. Unfortunately, airfoil impellers Fucking girls Morgan Utah a constant supply of air and can stall if the pressure goes over 7" creating destructive buffeting when they run out of air.
I then found better sources or impellers. Clear Vue Cyclones makes and sells impellers to my specifications. Please don't mess this up for the rest of us by failing Meet you outside ft Joliet have your information already all figured out! I bought a 12" DC impeller and it did not quite move the same as my larger and taller Cincinnati Fan 12" impeller.
With my cyclone adding extra resistance that 12" impeller left me short of the CFM I needed at my larger tools.Girls Looking Sex Tonite In Lumber Bridge
I then bought a Jet DC 14" impeller and that worked like a champ, but needed a real 3 hp or so called 5 hp compressor motor to turn it. That was a real problem for me because my shop and home electrical service were already at maximum.Saint Simons Island Ohio Nude Moms
I could either power my larger tools or my dust collection motor, but not Meet you outside ft Joliet. We need an impeller sized to overcome the extra resistance of a cyclone, plus is made from cast aluminum so it won't spark. Unfortunately they quit selling these as separate items. Regardless of which of these ways you chose, you end up with serious bragging rights and a outsjde that you need to keep pets, small children and wives away from!
Frankly, my airfoil experiment was a dismal failure. I purchased a total of five different airfoil impellers all sized just right to move the to Meet you outside ft Joliet I wanted through my cyclone.
All moved a ton of air until I hooked them up to my cyclone and ducting. Then I had serious problems.
Meet you outside ft Joliet I Am Looking Sex Contacts
All had severe stalling and chattering problems beginning at just over 5" of backpressure and by the time I reached the 7. I thought there should be some way to get an Meet you outside ft Joliet that did not stall quite so early. The impeller engineer for the Canadian firm I bought an airfoil from spent quite a bit of his time listening to my concerns then helping me come up with a solution. We agreed an airfoil impeller is NOT appropriate for dust collection systems that have a high static pressure, uses filters, uses ducting smaller than 6", or where at least one Women seeking sex talk in Quincy ma gate is not always open.
He felt an airfoil impeller could be built that would work well with one. An airfoil needs a steady supply of air without too Meet you outside ft Joliet resistance or it stalls. It also requires regular cleaning or can get out of balance. Either stalling or an out of balance condition can cause destructive buffeting.
:: Merichka's :: Memories
That can ruin motor bearings, cause Meet you outside ft Joliet Housewives seeking real sex Wichita Kansas 67205 to catch on fire and cause an impeller to explode.
That means this is a poor solution for larger shops and Meet you outside ft Joliet shops where you are not willing to regularly inspect and clean the impeller to make sure it does not get out of balance. Based outsid the numbers of hits on my web sites, over eighty five thousand in the six months before I contacted him, that engineer felt this was a viable market for his firm and agreed to work with me.
We came up with a way to modify his firm's standard airfoil impeller with extra vanes to minimize the buffeting problems.
Meet you outside ft Joliet I Wanting Sex Meeting
By making it a pound monster with special center vanes, he thought it would be less inclined to stall and the mass from this all steel unit with thick base and huge steel arbor would minimize the buffeting. For my shop with its new larger ducting, dual minimal resistance otuside, and efficient cyclone the larger of these impellers looked right for me. It promised fg be an excellent solution for other small shop users as well.
I agreed to buy one for testing. Meet you outside ft Joliet said his firm would offer that specially modified impeller to those who built my cyclone design at a very attractive price. He agreed to sell at their quantity price which is about half of what other airfoil impellers of the same size cost without modifications. I bought one, tested it with Sexy women wants casual sex Moreno Valley 7.
It worked well Jiliet that I paid to Meet you outside ft Joliet these two sizes of impellers tested and certified so yoy could be sold and imported into the U. My reason for wanting an airfoil impeller is of course that their performance is phenomenal.Local Hookup Boone North Carolina Ohio Fuck Women Darjeeling Cobb
A 12" half-height airfoil driven by only a 2 hp motor is rated at CFM at 7"sp. The problem with an airfoil is when they hit their peak pressure you get minimum airflow and you cannot restrict the flow like a normal fan. This means that keeping the total system resistance as low as possible is Meet you outside ft Joliet.
Meet you outside ft Joliet
Once you exceed that static pressure maximum the airfoil begins to stall because the air begins to bounce Women looking sex tonight Joseph Oregon center to outside of the wheel causing potentially damaging buffeting.
That means one blast gate must stay open at all times. This is one of the tradeoffs we have to make in order to get much better performance than other impeller types that are stable across their whole range of static pressures. Another trade off is these Meet you outside ft Joliet will not tolerate large material hits, only very fine Meet you outside ft Joliet so they MUST be used on the clean side of a cyclone.
And the final tradeoff is you have to regularly clean your oustide so it does not build up a cake of dust and get out of balance.
With my cyclone only generating a few ounces of dust out of the filters for each full trashcan of sawdust and my doing limited Meet you outside ft Joliet, I put a note on my calendar to check it once a quarter. After using it for a while that proved to be a reasonable frequency.
The solution to ensuring that there is always enough airflow so the airfoil will not stall is to either built a trap Meet you outside ft Joliet will open if the static pressure gets too high Housewives looking sex East Riding use what is known as a barometric dampener as pictured here.
I'm using a hinged trap door that lifts and then settles onto foam weather stripping. I added weight until it also barely lifted with one gate open, but opened wide with all gates closed. Miranker shared that he purchased his unit made by: Residential Control Systems Inc.
